Serena Williams of the US reacts during her final WTA tennis championships match against Russia’s Maria Sharapova in Istanbul, Oct 28, 2012.
Serena Williams’ motivating factor in her WTA Championships triumph on Sunday was to save her own sanity, the American said after beating Maria Sharapova in the final of the season-ending tournament.

Williams capped off a memorable 2012 on the circuit with a 6-4 6-3 victory as she claimed her seventh WTA title of year.
In a near faultless performance by the 15-times Grand Slam tournament champion, Williams never faced a break point during the final and was able to produce winners every time she was put under pressure by her Russian opponent.
The 31-year-old, who also lifted singles silverware this year at Wimbledon, the US Open, the London Olympics, Madrid, Charleston and Stanford, said it was important to end the season in style if only to preserve her mental state.
